Title: Constant-discharge pressure control pump
Inventor: YANO TOSHIO
IPC: F04B9/02
Filed: 1984-03-01
Abstract: PURPOSE:To make the discharge pressure of a pump controllable so constant, by installing a belt type stepless transmission in position between the pump and a motor, while shifting the motor in the running direction of a belt according to the pump's discharge pressure. CONSTITUTION:When the discharge pressure of a pump 2 goes up, pressure inside a diaphragm 15 also goes up, causing a valve stem 16 to go upward, whereby a valve plate 23 blocks up a valve port. With this closure, feed of a fluid flowing in a transfer cylinder 6 is stopped, and a piston member 6b is pushed back by dint of tensile in a belt 4, therefore a motor 1 shifts to the side of the pump 2. As a result, a distance between an input shaft 7 and a main shaft 25 of a belt type stepless transmission becomes short, loosening the belt to some extent, whereby a distance between both movable and fixed pulleys is shorted, and a pulley diameter grows larger instead, thus an input shaft of the pump comes to be rotated for deceleration.

Title: Lead-acid battery
Inventor: ONARI MASAHIKO
IPC: H01M10/06
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To prevent the loss of electrolyte by evaporation of moisture from the electrolyte surface of a lead-acid battery and improve the battery life by floating an oil on the electrolyte surface, and surrounding a positive electrode pole, corresponding to at least the upper limit position of a regulated electrolayte level to the lower limit position with a cylindrical body to prevent the contact of the oil with the positive electrode pole. SOLUTION: In order to avoid the contact of a positive electrode pole 5 with an oil 9, the size of a cylinder (cylindrical body) 12 is determined, so that the positive electrode pole 5 corresponding to at least the upper limit position of a regulated electrolyte level to the lower limit position is covered with the cylinder 12, so that the oil 9 does not make contact with the positive electrode pole 5 over the cylinder 12, even if the electrolyte level or oil position fluctuates. The electrolytic oxidation of the oil 9 is prevented thereby. Accordingly, the loss of electrolyte at a high-temperature use is suppressed, and a battery can keep a stable battery performance for a long time. In a widely used mono-block storage battery, only the positive electrode pole of the end cell may be isolated from the oil, and only the addition of oil is sufficient for the other cells.

Abstract: PURPOSE:To obtain a video disk reproducing device capable of rapidly outputting an image at the time of starting reproducing by writing a reproduced video signal obtained before the rotational speed of a disk reaches a reproducing speed in a memory and reading out and outputting the stored signal at a fixed period. CONSTITUTION:The video disk reproducing device is constituted so that a reproduced video signal obtained before the rotational speed of the disk 1 reaches the prescribed speed necessary for normal reproducing is written in video signal memories 15a, 15b and the reproduced video signals written in the memories 15a, 15b are read out and outputted at the fixed speed based upon clocks generated from an oscillator 8. In said constitution, time required for reproducing the video signal of one field from the disk is >=1/60sec before the rotational speed of the disk 1 reaches the prescribed speed necessary for normal reproducing, but the reproduced video signal can be outputted at the regulated period by reading out the signal from the memory in each 1/60sec after temporarily writing the signal in the memory 1. Thereby, even if the disk 1 rotates at a low speed at the time of its rising, an effective reproduced video signal can be outputted.

Title: Superconductive phototransistor
Inventor: NISHINO JUICHI
IPC: H01L31/10
Filed: 1986-02-27
Abstract: PURPOSE:To omit an element for amplification, by constituting a phototransistor by two sets of facing superconductive electrodes, which are provided on a semiconductor, a gate electrode, which is provided through said electrodes and an insulator, and the like. CONSTITUTION:A superconductive phototransistor is formed by facing superconductive electrodes 2 and 3 on a semiconductor 1, a gate electrode 5 through an insulating film 4, and the like. Since the phototransistor is used at a very low temperature, it does not become a carrier supplying source due to activation of impurities. Therefore, when light is projected on the gate 5, carriers are increased in correspondence with the excitation of the gate, and the superconductive current is largely varied by a minute incident signal. As a result, an element for amplification is not required, and the constitution and manufacture of the circuit can be simplified and become easy.

IPC: C21B5/00
Filed: 1983-03-11
Abstract: PURPOSE:To easily reduce the silicon content in hot metal at a low cost, by a method wherein the ambient temperature of furnace raceway is reduced by adding water into the blast at the vicinity of the tuyere. CONSTITUTION:When water is added to the blast at the vicinity of a blast furnace tuyere, heat is deprived from the blast air by the vaporization of water and the ambient temperature of furnace raceway is lowered. That is, when about 15kg water per unit ton of contents is added, the tuyere-nose flame temperature is decreased about 100 deg.C. The number of tuyere, in an injection manner, adding water shall generally be about one fourth to one half of total number of tuyeres and the additional amount of water should preferably be about 200l/H-1T/H. Thus, the generation of SiO2 gas is lessened and the silicon content of hot metal drops descending in the vicinity of tuyere raceway is reduced.

Title: Circuit for preventing frequency modulation inverting phenomenon
Inventor: MIKI SHIGERU
IPC: H04N5/922
Filed: 1983-03-11
Abstract: PURPOSE:To prevent a frequency modulation (FM) inverting phenomenon by detecting a rapid level change of a recorded video signal so as to decrease an FM recording level immediately before the change. CONSTITUTION:Suppose that a luminance signal A at an input terminal 1 has a rapid level change. The signal A is delayed by a delay circuit 2, and after the high frequency component is emphasized at a pre-emphasis circuit 3, the signal is FM-modulated by an FM modulation circuit 4. On the other hand, a point with the rapid level change, i.e. the high frequency component C is extracted at a BPF5 from the signal A, and the leading portion of positive polarity being a cause to the FM inverting phenomenon is detected D at a polarity detecting circuit 6. The detected output D becomes a control input to a gain adjusting amplifier 7, which is activated so as to decrease the level immediately before the FM- modulated output is changed from a high frequency to the low frequency region. As a result, since the level change is mitigated and even the portion where the level is low at the high frequency region becomes a waveform passing through zero cross points, no FM inverting phenomenon is generated.
